must be provided by a qualied electrician. All wiring must conform to local codes or latest edion of Naonal
Electrical Code ANSI/NFPA 70.
The branch circuit wiring should include either:
1. Metallic conduit or metallic sheathed cable approved for use as a grounding conductor and installed with ngs
approved for the purpose
2. Nonmetallic sheathed cable, metallic conduit or metallic sheathed cable not approved for use as a ground
conductor shall include a separate conductor for grounding. It should be aached to the ground terminals of the
water heater and the electrical distribuon box.
WARNING:
Proper ground connecon is essenal. The presence of water in the piping and water heater does not provide
sucient conducon for a ground. Nonmetallic piping, dielectric unions, exible connectors, etc., can cause the
water heater to be electrically isolated.
E. AMBIENT TEMPERATURE REQUIREMENTS
This unit is to be installed in an area where the ambient temperature is within 20°F - 120°F.

INSTALLATION INSTRUCTIONS
J. THERMAL EXPANSION
WARNING:
The water heater should not be installed in a space where liquids which give o ammable vapors are to be used or
stored.
Determine if a check valve exists in the inlet water line. It may have been installed in the cold water line as a
separate backow preventer, or it may be part of a pressure-reducing valve, water meter or water soener. A check
valve located in the cold water inlet line can cause what is referred to as a “closed water system.” A cold water inlet
line with no check valve or backow prevenon device is referred to as an “open” water system.
As water is heated, it expands in volume and creates an increase in the pressure within the water system. This acon is
referred to as “thermal expansion.” In an “open” water system, expanding water which exceeds the capacity of the
water heater ows back into the city main where the pressure is easily dissipated.
A “closed water system,” however, prevents the expanding water from owing back into the main supply line, and the
result of “thermal expansion” can create a rapid and dangerous pressure increase in the water heater and system
piping. This rapid pressure increase can quickly reach the safety seng of the relief valve, causing it to operate during
each heang cycle. Thermal expansion, and the resulng rapid and repeated expansion and contracon of
components in the water heater and piping system, can cause premature failure of the relief valve, and possibly the
heater itself. Replacing the relief valve will not correct the problem!
The suggested method of controlling thermal expansion is to install an expansion tank in the cold water line between
the water heater and the check valve (refer to the illustraon on right). The expansion tank is designed with an air
cushion built in that compresses as the system pressure increases, thereby relieving the over-pressure condion and
eliminang the repeated operaon of the relief valve. Other methods of controlling thermal expansion are also
available. Contact your installing contractor, water supplier or plumbing inspector for addional informaon regarding
this subject.
K. FILLING WATER
WARNING:
The unit must be COMPLETELY lled with water before being turned on. Failure to do so may permanently damage the
unit and will VOID manufacturer’s warranty. To check if the tank is full:
a. Ensure drain valve is shut ghtly
b. Open cold water inlet valve to ll the tank
c. Open hot water faucets slowly to allow air in the tank and piping to vent out
d. Smooth, undisrupted ow of water from the faucets indicates that the tank is full.
Turning the unit on when the tank is not completely full with water will cause water temperature to rise quickly and
trigger an alarm. If the alarm is triggered, turn the unit o and re-check that the tank is completely lled with water.

A. GETTING STARTED
How do I turn on the unit?
IMPORTANT: Before aempng to turn on the unit, please ensure the following:
1. Unit is connected to a dedicated 240V/60Hz single phase power outlet rated for at least 30 amperes. Conrm that
this power outlet is not being shared with another appliance. Conrm that the unit is grounded.
2. Condensate drains (primary and overow) are piped correctly to drain condensate.
3. Unit is COMPLETELY lled with water and there are NO LEAKAGES from any connecng port/valve. To check if the
tank is full:
a. Ensure drain valve is shut ghtly
b. Open cold water inlet valve to ll the tank
c. Open hot water faucets slowly to allow air in the tank and piping to vent out
d. Smooth, undisrupted ow of water from the faucets indicates that the tank is full.
You are now ready to turn the unit on by pressing the ‘ON’ buon in the Control Panel.
When the unit is o, the ‘OFF’ indicator in the control panel will be lighted. Please ensure the unit remains o unl the
tank is full with water.
Turning the unit on when the tank is not completely full with water will cause water temperature to rise quickly and
trigger an alarm. If the alarm is triggered, turn the unit o and re-check that the tank is completely lled with water.
B. OPERATING MODES
Which mode is right for me? How can I change the current mode?
The unit is preset to Auto mode. You may choose any of the following three modes depending on your hot water usage
and operang environment:
AUTO MODE (recommended): Auto mode runs the unit as a ‘hybrid’ to combine the eciency of a heat pump with the
high hot water delivery rate of an electric water heater. Average household hot water demand can be met by the heat
pump alone. However, if hot water demand were to rise above normal levels, the electric element is triggered to
supplement the heang provided by the heat pump.
ECON MODE: Econ mode is the most energy ecient mode in the unit. In this mode, electric element is deacvated
and water is heated exclusively by the heat pump to maximize energy eciency. While the Econ mode is factory set to
run anyme during the day to meet hot water demand, users have the opon to congure the mer feature to allow
the unit to run during chosen me periods only (users may select up to 3 operang me periods in a 24 hour cycle).
This mode allows users to take advantage of o-peak power tari rates.
HEATER MODE: In the Heater mode, heat pump is de-acvated and water is heated by electric element only. Please
note that Heater mode will automacally revert to Auto mode within 48 hours of the Heater mode being acvated (48
hours is the default seng – users may choose any duraon from 12 to 999 hours). Users may select Heater mode to
temporarily deacvate the heat pump and stop cold air exhaust and/or operate the unit at a lower noise level.
Press MODE buon to select or switch between any of the three modes.

OPERATING INSTRUCTIONS
C. SETTING WATER TEMPERATURE
What water temperature seng is right for me? How can I change the temperature seng?
The maximum temperature seng on the unit is 135 degrees. Recommended water temperature seng range is
120-125 degrees – this is both to maximize eciency and contain hot water scald risk.
AirGenerate™ recommends that users start with a lower temperature seng (120 degrees) and increase the
temperature seng only if the current temperature seng is unable to cope with hot water demand.
The unit is equipped with two water temperature sensors, one each at the top and boom half of the unit. The
temperature shown in the display panel is the lower sensor reading. You may check the upper sensor reading by
holding down the up arrow buon.
To change the water temperature seng, hold down the TIMER buon unl the set temperature indicator on the
display panel starts ashing. Use the ARROW PADS to select the new seng and press the TIMER buon to save the
selecon. You may choose any temperature between 90 to 135 degrees.
D. DUCTING EXHAUST AIR
Can I duct the exhaust air from the unit? What are the benets of the ducng the exhaust air?
The unit has an exhaust air outlet that can be connected to a 6-inch duct. The cool exhaust air, a free by-product of
heat pump operaon, can be ducted to any part of the home. It can also be used to supplement home cooling, saving
you addional energy on home cooling costs during summer months. You may vent the exhaust air out of the home
during winter months.
Ducng is especially recommended if the install area is less than 1,000 cubic feet in volume or if the unit has low
overhead clearance.

E. COLD CLIMATE OPERATION
Does the heat pump work eciently in cold climate? Do I need to switch modes based on seasonal changes?
The heat pump is designed to operate even in sub freezing temperatures.
Heat pump eciency and hot recovery rate are aected by ambient temperature. If you are running the unit in Econ
mode and nd that the unit is not able to cope with hot water demand during winters switch to Auto mode during
winters and revert to Econ mode during summers. Auto Mode works eecvely throughout the year.

MAINTENANCE
A. T&P / RELIEF VALVE
The relief valve is an important safety feature and should be checked at least once a year. You may li the lever handle
to release water from the unit and ensure that the valve is operang normally.
CAUTION:
Since the relief valve may release hot water from the unit, the water should be released directly into a suitable drain.
The relief valve should not be removed, plugged or obstructed under any circumstance.
B. FILTER
The air intake to the heat pump goes through a lter to safeguard the unit from dirt and dust. The lter is washable
and it is recommended that it be cleaned or rinsed every 2 years. Filter can access through the lter cover on top of the
unit. Please follow Fig. 7 instrucons to access the lter.
C. ANODE ROD
The unit comes pre-aached with a sacricial anode rod to counter corrosive elements in the tank. Anode rods deplete
over me and it is recommended that the anode rod in the unit be checked every two years. If the anode rod is found
to be depleted, replace the anode rod. A DEPLETED ANODE ROD WILL RESULT IN TANK FAILURE. Please follow Fig. 7
instrucons to access the anode rod.
D. SEDIMENT BUILD-UP
Sediment build-up is a common occurrence on all water heaters. Since sediment deposits in the tank of the unit can
aect performance and compromise safety, it is recommended that the tank is drained periodically. AirGenerate™
recommends draining a few quarts of water every month and draining the unit completely every year.
CAUTION:
Shut o the power to the unit before draining the unit, even if you are draining a few quarts of water only. To drain
the unit completely, shut o the cold water supply and open hot water faucet(s). Unit must be drained by opening
the drain valve located at the boom of the unit.
WARNING: RISK OF ELECTRIC SHOCK
MAKE SURE THE UNIT IS COMPLETELY SHUT OFF AND UNPLUGGED FROM POWER SOURCE.
E. CONDENSATE DRAIN TUBE
The unit is equipped with two condensate water drains – a primary drain and an overow drain. A monthly check is
recommended to ensure that the hoses are securely connected to the drains and the hoses are not kinked or clogged.
The primary condensate drain hose should slope downward to ensure that condensate is drained eecvely.
Condensate ow through the overow drain hose is an indicaon that the primary condensate drain is clogged. If
